Chinese telecommunications-equipment maker Huawei Technologies Co. Ltd. is making inroads in the U.S., a market it has previously had trouble cracking because of competition from Western rivals and national-security sensitivities.

The company has won a contract to supply the network infrastructure for a cellphone service that cable-TV provider Cox Communications Inc. plans to launch in some markets later this year, people familiar with the matter say.
